Thread: Water ingress air compressor area?

Hi all,

We have just returned from a long Gibb River road trip - more on that later.

The car has developed a weird fault, where it claims pressure rising too slowly, but only if the compressor is running when we enter a deep crossing. Usually the case, as I would press off-road mode before entering (roads are too fast to stay in off road the whole time)

Some fault finding and investigation to date:

Multi pin connector in the compressor housing was run poorly, ‘stretching’ to reach. I’ve rerun over the top of the compressor in case the seals weren’t quite sealing, no change

I tried raising and lowering the car, and all works fine. It’s quick, and when dry, I don’t get the fault

If I wait for the compressor to finish filling the tank before entering the water (ie, gallery pressure back to 200 kpa following a short exhaust sound) I don’t get the fault

I’ve reseated the pressure switch connector too - thinking if the water caused this to short to zero, may be interpreted as zero pressure, bringing up ‘too slowly’ errors. No change

I’ll get the car home in a week or two, and will take another look, maybe use some electrical cleaner to clean any buried corrosion on the plugs. Is there any product out there to rejuvenate seals?

Otherwise, is there anything else that may be playing up?

The crossings weren’t crazy deep, maybe 600mm, and long beyond anything we will see in town, but I’d like to know it is all in order, lest it deteriorate without knowing to become a bigger issue

Yes, sorry - meant the seal on the various electrical plugs. I’ll try the dielectric stuff

I’ve ordered a refurb kit for both the compressor and the valve blocks, so giving the whole system something of a birthday when back home!
